Below is my error which i get while i compile AppleComputer class file ( shown down below).

Any help solving this error would be appreciated .

Thanks

Your displayComputerInfo() method is calling methods on Computer as if they are static, because you typed Computer instead of computer - different case. Gotta watch case-sensitivty in Java :)
